Theory of Operation

This section describes the electrical operation of the video measurement setusing the major circuit blocks or modules.

This section is divided into the following parts:

� Logic Conventions describes how logic functions are discussed andrepresented in this manual.

� Block Level Description describes circuit operation to the functional blocklevel.

� Detailed Circuit Description on page 3–3 describes circuit operation to thecircuit and component level.

Logic ConventionsThis manual refers to digital circuits with standard logic symbols and terms. Alllogic functions use the positive-logic convention: the more positive of the twologic levels is the high state, and the more negative level is the low state. Thespecific voltages that constitute a high or low state may vary among theelectronic devices.

A back slash prefixed to the signal name (/RESET) indicates active-low signals.Signal names can be either active high, active low, or have both active-high andactive-low states.

Block Level DescriptionRefer to Figure 9–2, the detailed block diagram found on page 9–4, whenreading the block-level description. The description explains the basic operationof each circuit block. If you need more detailed information, refer to the DetailedCircuit Description on page 3–3 and the component-level circuit diagramsfound in the Diagrams section.

The DC Restore circuit selects AC or DC input coupling and clamps thebackporch level of the video signal when AC coupling is active. To terminate theINPUT the user must install a 75 � device to the unused INPUT connector.

The Sync Stripper consists of a reference select circuit and three sync separators.The reference select circuit chooses either the INPUT video signal or an externalsignal for the sync reference. The sync separator uses the selected sync referenceto generate composite, vertical, and horizontal sync signals.

DC Restore

Sync Stripper

Theory of Operation


The Gain, DC Offset, and Filtering block provides signal processing to the inputvideo signal. The circuit selects one of three input filters, and also provides ananti-aliasing filter to remove unwanted signal components from the A/DConverter input. Under host processor control, the circuit provides fixed gain,variable gain, and variable DC offset for the video signal.

The Phase Lock Loop synchronizes signals within the video measurement set toa known reference. Either the video signal from the INPUT, or an externalreference applied to the EXT REF input, can be used. The Phase Lock Looplocks to either the sync or burst signals.

The Analog-to-Digital (A/D) Converter converts the analog video signal into10-bit digital words. The conversion rate is 8 times the subcarrier frequency.

The Digital Signal Processor (DSP) system is a coprocessor that makes rapidcalculations using the acquired data. Processed waveform data from the DSP isavailable for use by the host processor.

The Acquisition Control stores data from the A/D Converter into waveformmemory. It also controls the real-time aspects of acquisition such as busarbitration phase lock operation, gain and DC offset settings.

The host processor controls the main operating system functions includingacquisition, front panel control, and the LCD display. The operating systemstored in Flash EPROM can be upgraded through the RS232 port using anexternal PC controller.

The Remote Interface (RS232) drives the rear-panel RS-232 connector forremote operation.

The Front Panel contains a 13-switch keypad and 8 LED indicators. The hostprocessor reads the front panel registers to detect switch closures, and writes tothe registers to change the status of LED indicators.

The LCD Display provides displays of the measurement results, signal identifi-cation codes, and configuration parameters. The host processor provides signalsto control the display and set the LCD viewing angle.

The Power Supply provides +12 V, –12 V, and +5 V.

Detailed Circuit DescriptionThis detailed circuit description explains the function of each major circuit. Use this description to help you isolate faults when troubleshooting. As you readthe description, refer to the component-level circuit diagrams found in theDiagrams section.

The DC Restore circuit (diagram 1 ) consists of the Video Input and InputAmplifier. These circuits combine to perform the following functions:

� Select AC or DC input coupling

� Clamp the backporch level of the video signal

Video Input. The video signal to be measured connects to loop-through INPUTconnectors at either J30 or J31. The unused connector must be terminated with75 �. Transistors Q2 and Q3 establish the coupling mode. When the AC/DCSEL line is high, C58 AC-couples the signal to amplifier U17. AcquisitionControl FPGA U99 (diagram 4 ) controls the AC/DC SEL line. Switchingoccurs to accommodate the requirements of signal measurement modes.

Input Amplifier. Input Amplifier U17 (diagram 1 ) clamps the backporch level ofthe video signal. Signal clamping determines the DC level measured at TP9.When the amplifier is operating, the DC level at TP9 is equal to the videobackporch level at U17 pin-3, minus the voltage across sampling capacitor C13.An operational amplifier within U17 performs the subtraction using R60 to feedback the sample-and-hold output (buffered voltage on C13) to pin-1, the negativeinput of the operational amplifier.

The CLAMP_PLS signal (from U31, diagram 2 ) goes low during thebackporch interval while U17 and C13 sample and hold the back porch level ofthe incoming video. As a result, the backporch level of the clamped video is zerovolts. The OFFSET signal from U30C (diagram 4 ) can then control thenegative input (pin 6) of the sample-and-hold amplifier to establish the DC levelof the clamped video.

When switch U18A is closed, the DC restore circuit is disabled. TheDCREST_ON signal from U99 (diagram 4 ) disables the DC Restore circuit.When the switch is closed, sampling capacitor C13 charges to the OFFSETvoltage. As a result only the OFFSET voltage is subtracted from the input videosignal, under normal conditions the sum of the backporch level and the OFFSETvoltage are subtracted.

DC Restore

Theory of Operation


The Sync Stripper (diagrams 1 and 2 ) consists of a Reference Select circuitand three Sync Separators. The Reference Select circuit chooses either theinternal video signal or an external signal for the sync reference. The SyncSeparators use the selected sync reference to generate composite, vertical, andhorizontal sync signals.

Reference Select. The selected sync reference signal controls video timing withinthe video measurement set. Video switch U14 selects either the INT VIDEOsignal or an external signal connected to the EXT REF input. The INT/EXTsignal from U99 (diagram 4 ) controls U14. When INT/EXT is high, the INTVIDEO signal is selected.

Composite Sync Separator. The REF_VIDEO output from U16 drives pin-12 ofcomposite sync separator U6. From this input, U6 generates the COMP_SYNC(horizontal and vertical composite synchronization) and BPSAMP (back porchsample) signals at pin-24 and pin-28, respectively.

An AGC (automatic gain control) circuit within U6 compensates for low- orhigh-gain input signals. Capacitor C55 samples and provides feedback of thesync amplitude for the AGC circuit.

Vertical Sync Separator. Active filter U85A filters the COMP_SYNC signal, andthe combination of CR86, R172, and C213 provide envelope following. Thefilter integrates the broad pulses of the vertical interval so that during the verticalsync interval, the filter output goes lower than the output of the envelopefollower. For PAL signals, a low NTSC/PAL signal from U99 (diagram 4 )increases the filter time constant by adding C24 to the filter.

Comparator U85B compares the input and the output of the envelope follower.Buffer U87A buffers the output and shifts the logic level for CMOS compatibili-ty. The resulting FIELD signal (at TP16) reflects the vertical sync rate.

Horizontal Sync Separator. U31 (diagram 2 ) uses the COMP_SYNC signal togenerate the horizontal sync (HSYNC) signal. HSYNC is output on pin 8.

Figure 3–1 shows a simplified diagram of the Gain, DC Offset, and Filteringblock. This block provides signal processing to the input video signal. It consistsof the the Filter Select and Analog Processing circuits, which perform thefollowing functions:

Filter Select. Multiplexer U10 (diagram 1 ) selects one of three filtered signalsto drive the A/D Converter: INT VIDEO (flat), CHROM (chrominance), andLUM (lowpass). Control lines FILTER0, FILTER1, and FILTER2 from U99(diagram 4 ) select the filter.

The flat filter output signal (INT VIDEO) is taken directly from pin-14 of inputamplifier U17. Operational amplifiers U13 and U14 form a lowpass filter used togenerate the LUM signal for the hum measurement. Buffer U20 and itssurrounding components form a bandpass filter to generate the CHROM(chrominance) signal.

Analog Processing. The Analog Processing circuit controls gain and offset. Thecircuit also filters the video signal before routing it to the A/D Converter. AGilbert gain cell within U5 provides variable gain, and switches within U5control fixed gain. The VARGAIN signal from U29C (diagram 4 ) controlsvariable gain, while GAIN0 and GAIN1 from U99 control fixed gain.

The Analog Controls circuit (U29D) generates the POSITION signal to rapidlychange the DC offset at the output of U5. The OFFSET signal (U17 pin-6) alsoadjusts DC offset but has a slower response time because it serves as thereference for the DC Restore circuit.

After U5 sets gain and DC offset, buffer U9 converts the current output signal toa voltage. The signal is then applied to an anti-aliasing filter consisting ofinductors L11, L12, and the surrounding components. The filter removes signalcomponents whose frequencies exceed 4-times the subcarrier frequency (theNyquist frequency at the 8-times subcarrier frequency sampling rate of the A/DConverter).

The LIMIT signal generated by U84 provides status information to the Acquisi-tion Control circuit (diagram 4 ). If the video signal limits due to low or highsignal amplitude, the LIMIT signal goes high.

Theory of Operation


The Phase Lock Loop circuit synchronizes signals within the video measurementset to a known reference. Either the video signal from the INPUT, or an externalreference applied to the EXT REF input can be used. The Phase Lock Loopcontains circuits for locking to the sync and burst signals.

The Phase Lock Loop circuits use a common voltage-controlled crystal oscillator(VCXO). They also contain phase detectors, a counter/divider circuit forsynthesizing burst, h-sync, and a multiplexer for selecting either subcarrier burstphase error or horizontal synchronization phase error signals.

VCXO. VCXO Y1 (diagram 2 ) is the controlled oscillator within the loops. Thecrystal frequency is 28.63636 MHz for the VM100 and 35.46895 MHz for theVM101. Control line SYNC/BURST from U31 selects which error voltagesource (sync or burst) will control the VCXO through switch U120.

The output of the VCXO is a 50% �5% duty cycle square wave at 8-times thesubcarrier frequency. Comparator U116 buffers the VCXO output to create bothpositive (8FSC_IN) and negative (/8FSC_IN) polarities with very low timeskew.

Buffer U12A and comparators U113C and U113D form a window comparatorthat senses when a loop is unable to achieve lock. When the error voltage atTP19 reaches either the upper (+4 V) or lower (+1 V) limit, U113C or U113Dsets the /PLL RANGE signal low. When this occurs, U31 attempts to close theloop. If unable to reestablish a locked loop, U31 asserts the /UNLOCKED line toalert the acquisition system of the unlocked condition.

U31 generates miscellanious video line-based timing signals for use duringacquisition. It also generates the 2 MHz square wave DSP_RCK signal. DSPU48 (diagram 3 ) uses the DSP_RCK signal as its phase-lock loop input. TheDSP clock has a known frequency relationship to the sample (A/DC) clock whenit locks to the DSP_RCK signal.

Sync-Locked Loop. Error amplifiers U26A and U26B form the horizontalsynchronization signal (h-sync) phase detector for the Sync-Locked Loop. Whenin sync locked mode, U31 sets the SYNC/BURST signal high to control theVCXO from U26B pin-7.

Within U31, the 8FSC_IN signal from U116 is divided to one-half the h-syncfrequency. The HSYNC signal is also divided by two within U31. Both signalsare applied to a phase detector that produces outputs on pin-4 and pin-5 to driveerror amplifier U26A.

Burst Locked Loop. The Gilbert multiplier section of U118 serves as the burstphase detector for the Burst Locked Loop. U118 detects errors between theREF_VIDEO signal and the synthesized FSC burst frequency signal from U31.

Phase Lock Loop

Theory of Operation


After level shifting and buffering by Q7, Q6 and U12B, the phase error signalpasses through switch U120 to control the VCXO. U31 sets the SYNC/BURSTsignal low to close the switch.

U31 generates the BP_GATE signal by counting the 8FSC_IN signal edges withreference to HSYNC. The BP_GATE signal gates the burst phase detectorthrough gates U119A and U119B. To achieve lock, U31 divides the 8FSC_INsignal from the VCXO to the subcarrier frequency, producing the FSC and /FSCsignals which are compared to REF_VIDEO by phase detector U118.

A/D Converter U22 (diagram 3 ) converts the VIDEO signal into 10-bit digitalwords. The conversion rate is 8-times the subcarrier frequency, controlled by the8FSC signal. During acquisition, Aquisition Control FPGA U99 (diagram 4 )enables tri-state buffers U38 and U39 to drive the DSP data bus with the A/DConverter output. The A/D Converter is part of the Acquisition and DSP systemwithin the video measurement set. Figure 3–2 shows a simplified view of thesystem.

Figure 3–2: Acquisition and DSP system

The Digital Signal Processor (DSP) system is a coprocessor that makes rapidcalculations using the acquired data. It follows instructions provided by the hostprocessor to process the waveform data, and to make the data available to thehost processor.

The DSP system consists of the following circuits:

� Acquisition Memory

� X/Program Memory

� Digital Signal Processor (DSP)

Acquisition Memory. The Acquisition Memory (U57, U96, and U97 on diagram3 ) stores the signal amplitude (Y-axis) data output by A/D Converter U22. The

A/D Converter writes data words to Acquisition Memory through tri-statebuffers U38 and U39. The host processor also accesses Acquisition Memory

Digital Signal Processor(DSP)

Theory of Operation


through tri-state transceivers U41, U42, U43, U44, and U46. The memory is24-bits wide and 64K words deep. It resides in the native Y-memory space ofDSP U48 and the host processor.

X/Program Memory. The X/Program Memory (U93, U94, U95 on diagram 3 )stores the DSP program provided by the host processor and the address locations(X-axis) of the acquired signal data. The host processor also accesses AcquisitionMemory through tri-state transceivers U41, U42, U43, U44, and U46. TheX/Program memory is 24-bits wide and 64K words deep.

Digital Signal Processor (DSP). Digital Signal Processor (DSP) U48 (located ondiagram 3 ) is a coprocessor that makes rapid calculations using the acquireddata. The DSP communicates directly with the host processor through its hostport located in host memory space. The DSP also communicates with the hostprocessor by writing measurement results to X-memory and signalling the hostto read it. Acquisition Control FPGA U99 (diagram 4 ) controls bus arbitration,a process that removes the DSP from the bus during acquisition and host access.

The host processor loads the DSP program into DSP program memory (U93,U94, and U95). After the program is loaded, it begins with initialization whichincludes the following tasks:

� Program the internal phase lock loop (U31 on diagram 2 ) to lock to the

DSP_RCK signal. (When locked, LED DS1 on diagram 3 turns on.)

� Copy internal X-constant and Y-constant data from external X-memory andY-memory, if needed

After initialization, the DSP waits for host commands through the host port.

Acquisition Control FPGA U99 (diagram 4 ) stores data from the A/DConverter into waveform memory. It also controls the real-time aspects ofacquisition including the following:

� Implement bus arbitration between the DSP, host processor, and A/DConverter

� Control settings for the Gain, DC Offset, and Filtering block and the PhaseLock Loop

� Check the status of the Gain, DC Offset, and Filtering block and the PhaseLock Loop

Acquisition Control FPGA U99 counts video lines and fields based on theHSYNC and FIELD signals from the Sync Stripper circuit. The host processorprograms registers within U99 that control the following parameters:

� Line and field where acquisition will start

� Number of lines to acquire

Host Processor andMemory

Theory of Operation


� System memory bus, which includes SRAM (U71, U72, U103, and U108),NVRAM (U100), and Flash EPROM (U101 and U102)

� DSP bus, which includes DSP U48, Acquisition Control FPGA U99,Acquisition Memory, and X/Program Memory

Reset circuit U79 (diagram 5 ) synchronizes the system reset function andensures that the host processor powers up to a known state. The +5 V supplyconnects to U79 pin-7. When power is turned on, U79 holds the /RST signal onpin-5 low until the +5 V supply reaches a safe operating level. The /RST signalcontrols the host processor reset (U80 pin-69). If the +5 V supply drops belownormal limits, U79 asserts the /RST line low so the host processor can initiatethe power-down sequence. Buffer U66A routes the /RESET signal to DSP U48,Acquisition Control FPGA U99, and RS-232 DUART IC U115.

The host processor performs system diagnostics during the power-on sequence.When power is turned on, the reset circuit (U79) ensures that the host processorpowers up to a known state. The host processor then runs the program in bootROM U61 to execute the diagnostics as shown in Table 3–1.

Table 3–1: Power-on diagnostics

The host processor communicates with the RS-232 port through DUART ICU115 and RS232 transceiver U112 (diagram 6 ). DUART IC U115 converts8-bit parallel data from the host processor to serial data for transmission. It alsoconverts serial data received from the remote interface to 8-bit parallel data.

In addition to buffering the data, DUART IC U115 generates an interrupt onIRQ5 whenever data is received or transmitted. Transceiver U112 convertssignals to the levels required for internal and external devices. DUART IC U115requires CMOS levels and external devices require RS232 logic levels.

Remote Interface (RS232)

Theory of Operation


Rotary switch S1 controls the RS232 serial interface pin selection for the TX(Transmit Data) and RX (Receive Data) lines. The switch is set at the factory tothe clockwise position (pointing to DEFAULT label on the circuit board).

The front panel board (A1) contains a 13-switch keypad and eight LEDindicators. The host processor reads and writes the control data through atwo-way serial bus. Once every 20 ms, the host processor latches the keypad datainto shift registers U2 and U3 (diagram 8 ). The host processor then clocks U2and U3 to generate the serial FPMISO signal, which it reads to determine theswitch status. Each closed switch produces a low bit within the serial FPMISOstring. When LED status changes are required, the host processor loads shiftregister U1 with an 8-bit control string (BMOSI).

Buffer U74 (diagram 6 ) routes the clock and serial data to the front panelboard (A1). Decoder U75 performs the address decoding for the serial bus.

The LCD board (A4) contains the LCD display (diagram 6 ). Built-in driverson the board connect to the microprocessor bus as an 8-bit port. Shift registerU122 lengthens and inverts the chip select signals for compatibility with theLCD. The LCD_ANGLE signal from U30D (diagram 4 ) controls the LCDviewing angle as viewed from top to bottom.

The power supply board (A3) supplies +12 V, –12 V, and +5 V to the mainboard (A2). Voltage regulators on the main board (diagram 7 ) post-regulate the+12 V supply to +8 V, and the –12 V supply to –8 V and –5 V.

A switching regulator consisting of U124 and Q123 provides greater efficiencyfor the –5 V supply. Switching regulator U124 turns on FET pair Q123 oftenenough to charge C293 to an average of –5 V. This forces VFB at pin-2 to equalthe VREF level at pin-8. A second-order filter formed by L21 and C290 passesthe average (low frequency) value to pin-2 (VFB) of U124 through amplifier Q9and resistors R365 and R366. L20 and C289 provide additional filtering.

To restore the previously saved calibration data, turn off the video measurementset and then turn it on again.

When using the built-in adjustment procedure, you will not manually adjust thecircuits. Instead, the video measurement set adjusts its internal circuits usingexternal DC voltages you provide in response to prompts on the LCD display.Your role is to connect the test signals and to instruct the video measurement setto continue. Upon successful completion of the adjustment procedure, the videomeasurement set automatically loads the new calibration data into memory.

Perform the following steps to adjust the video measurement set:

1. Connect the equipment as shown in Figure 5–1.

NOTE. Do not connect a 75 � terminator to the INPUT connector unless yourvoltage reference can supply more than 10 mA.

If the voltage reference output is current-limited, the terminator may attenuatethe output voltage, causing the adjustment procedure to fail.

Maintenance

This chapter contains the information needed to do periodic and correctivemaintenance on the video measurement set. The following sections are included:

� The Maintenance section provides general information on preventingdamage to internal modules when doing maintenance, lithium batterywarnings and disposal instructions, and procedures for inspecting the videomeasurement set and cleaning its external and internal modules.

� The Removal and Installation Procedures (page 6–7) provide procedures forthe removal and installation of modules.

� Troubleshooting (page 6–17) provides information for isolating failedmodules. Included are power supply parameters, and examples of waveformsmeasured at key test points within the video measurement set.

� Repackaging Instructions (page 6–33) provides packaging information forshipment or storage.

Preventing ESDWhen performing any service that requires internal access to the video measure-ment set, adhere to the following precautions to avoid damaging internalmodules and their components due to electrostatic discharge (ESD).

CAUTION. Static discharge can damage any semiconductor component in thisvideo measurement set.

Minimize handling of static-sensitive modules.

Transport and store static-sensitive modules in their static protected containers oron a metal rail. Label any package that contains static-sensitive modules.

Discharge the static voltage from your body by wearing a grounded antistaticwrist strap while handling these modules. Do service of static-sensitive modulesonly at a static-free work station.

Nothing capable of generating or holding a static charge should be allowed onthe work station surface.

Handle circuit boards by the edges when possible.

Do not slide the modules over any surface.

Maintenance


Avoid handling modules in areas that have a floor or work-surface coveringcapable of generating a static charge.

This instrument contains electrical components that can be damaged by staticdischarge. See Table 6–1 for the relative susceptibility of various classes ofsemiconductors. Static voltages of 1 kV to 30 kV can occur in unprotectedenvironments.

Table 6–1: Relative susceptibility to static discharge damage

Linear microcircuits 400 to 1000 V

Low power Schottky TTL 900 V

TTL (Least Sensitive) 1200 V

Battery DisposalDispose of lithium batteries according to local, state, and federal regulations.

WARNING. To avoid personal injury, observe the proper procedures for handlinglithium batteries.

Improper handling can cause fire, explosion, or severe burns.

Do not recharge, crush, disassemble, heat above 100° C (212° F), incinerate, orexpose the battery to water.

The video measurement set contains one lithium battery, A2U100, located on themain board (A2). Battery replacement is accomplished by replacing A2U100 orby installing a new main board (A2). Read the following information beforereplacing the battery. See lithium battery on page 6–16 for replacementinstructions.

Maintenance


Inspection and CleaningInspection and cleaning are done as preventive maintenance. Preventivemaintenance, when done regularly, may prevent malfunctions and enhancereliability.

Preventive maintenance consists of visually inspecting and cleaning the videomeasurement set, and using general care when operating it.

How often to do maintenance depends on the severity of the environment inwhich the video measurement set is used. A proper time to perform preventivemaintenance is just before adjustment of the video measurement set.

The top cover keeps dust out of the video measurement set and should be inplace during normal operation.

Inspect and clean the video measurement set as often as operating conditionsrequire. The collection of dirt on internal components can cause them to overheatand breakdown. Dirt acts as an insulating blanket, preventing efficient heatdissipation. Dirt also provides an electrical conduction path that could cause avideo measurement set failure, especially under high-humidity conditions.

CAUTION. Avoid the use of chemical cleaning agents that might damage theplastics and external labels used in the video measurement set.

Use a cloth dampened with water to clean external surfaces.

Use a cloth dampend with a 75% isopropyl alcohol solution to clean internalsurfaces.

Before using any other type of cleaner, consult a Tektronix Service Center ortechnical representative.

Inspection — Exterior. Inspect the outside of the video measurement set fordamage, wear, and missing parts. Use Table 6–2 as a guide. Instruments thathave been dropped or otherwise abused should be checked thoroughly to verifycorrect operation and performance.

Troubleshooting the main board (A2)This section provides the following troubleshooting information for locatingfaults on the main board (A2):

� Power on diagnostics

� Examples of analog signal measurements

� Phase lock and DSP diagnostic LEDs and key signals

� ACQ:SHOW command

� Troubleshooting the VM140 or VM141 System

The host processor performs a limited set of system diagnostics during thepower on sequence. When power is turned on, the reset circuit (U79) ensures thatthe host processor powers up to a known state. The host processor then runs theprogram in boot ROM U61 to execute the diagnostics as shown in Table 6–5.Use the results of the power-on diagnostics to locate faults within the hostprocessor system.

See Figure 6–10 to locate the power on diagnostics LED DS2.

By connecting a test signal to the INPUT connector, you can use an oscilloscopeto measure waveforms in the signal path up to the A/D Converter. Compare yourmeasured waveforms to the example waveforms in this section to determine ifthe analog section of the main board (A2) is functioning properly.

You can also measure the output of A/D Converter A2U22 using an oscilloscope.When you apply a luminance ramp signal to the INPUT of the video measure-ment set, the output bits from A2U22 toggle at increasing rates. The leastsignificant bit (pin 16) toggles at the fastest rate and the most significant bit(pin 28) toggles at the slowest rate. Trigger the oscilloscope on the /ACQUIREsignal (A2TP34 or A2U39 pin 1) for best results.

NOTE. The example waveforms are PAL format signals taken from a VM101. Ifyour video measurement set is a VM100 (NTSC), the waveforms you measurewill have a different horizontal scale.

Perform the following steps to measure the example waveforms shown inFigure 6–12 through Figure 6–16. Refer to the circuit board illustrations in theDiagrams section for test point locations.

1. Connect the test equipment as shown in Figure 6–11.

Troubleshooting


Figure 6–16: FIELD waveform at A2TP16

The main board (A2) contains two LEDs, DS1 and DS3, that indicate the statusof the Phase Lock and DSP circuits. See Figure 6–10 on page 6–21 for thelocation of each LED. Under normal conditions DS1 (DSP) is on and DS3(Phase Lock) is off.

NOTE. If the video measurement set is configured for an external reference and asuitable signal is not connected to the EXT REF input, DS3 will turn on.

DS1. Indicator DS1 lights when the video measurement set is ready to acquire asignal. A signal does not need to be connected to the INPUT connector. If DS1fails to light, either the DSP phase lock loop is not working or the host processorhas failed to program the DSP.

To isolate the fault, test the Phase Lock circuit operation as described below. Ifthe Phase Lock circuit is operating correctly, the fault is most likely in theDSP/Data Acquisition circuits that include A2U48, A2U99, and their surround-ing components.

DS3. Indicator DS3 lights when the video measurement set is unable to achievephase lock. If DS3 is illuminated, check for the following signals (refer to thecircuit board illustrations in the Diagrams section for test point locations):

� DC voltage between +1 V and +4 V at measured at A2TP19

� Video signal with burst and sync components measured at A2R353 (similarto Figure 6–12 on page 6–23)

� The COMP_SYNC signal measured at A2TP15 (see Figure 6–15)

� HPULSE measured at A2TP18 (see Figure 6–18)

� DSP_RCK measured at A2U48 pin 1 (see Figure 6–19)

� The 8FSC_IN and /8FSC_IN signals measured at A2U116 pins 7 and 8 (seeFigure 6–17)

NOTE. The 8FSC_IN and /8FSC_IN signals are 180° out of phase, but otherwiseidentical. Figure 6–17 only shows an example of the 8FSC_IN waveform.

Digital control signals such as NTSC/PAL and SYNC/BURST (A2U31 pins 36and 74, respectively) can also cause the Phase Lock circuit to fail. Check fordigital control failures if DS3 is illuminated but you measure correct testwaveforms.

Troubleshooting


The ACQ:SHOW command is a remote command you can send to test thefunctionality of the video measurement set. The command causes the hostprocessor to transfer a coarse representation (approximately 24 × 80) of thesignal from memory to the PC display (Figure 6–20).

NOTE. The ACQ:SHOW command is only intended for use by qualified servicepersonnel when troubleshooting the video measurement set. Do not use thecommand for any other video measurement set applications.

If you are not able to send the ACQ:SHOW command (the RS-232 does notfunction properly), verify that rotary switch A2S1 is set fully clockwise (pointingto DEFAULT label on the circuit board).

Figure 6–20: Example of the ACQ:SHOW command PC display

The ACQ:SHOW command isolates failures within the host processor and DSPcircuits. If the PC displays the ACQ:SHOW waveform correctly, the hostprocessor is able to access RAM and successfully read data from and write datato the RAM; the failure is most likely in the DSP circuit.

If the PC cannot display the ACQ:SHOW waveform and you can measure theanalog waveform at the A/D Converter input, the failure is most likely in thehost processor or in the acquisition circuits.

ACQ:SHOW Command

Troubleshooting


NOTE. Under some conditions, the host processor and memory circuits could failand still allow the PC to display the ACQ:SHOW waveform.

To display the ACQ:SHOW waveform on a PC, perform the following steps:

1. Connect the equipment as shown in Figure 6–21.

Figure 6–21: Setup for using the ACQ:SHOW command

2. Run the terminal emulator or communication program on the PC.

NOTE. To avoid data transfer problems, do not use a file transfer protocol suchas Kermit or XMODEM.

3. Configure the video measurement set RS-232 serial port for computeroperation.

4. Configure the video measurement set RS-232 parameters to match therequired settings for your computer.

NOTE. Refer to your computer manual to determine the settings for baud rate,stop bits, parity, and flow control.

5. On the TV signal generator, set the output for a video signal in the correctformat for your video measurement set (NTSC or PAL).

6. Send the following command to the video measurement set:

ACQ:SHOW f1,8

7. Check the PC display for the ACQ:SHOW waveform (Figure 6–20).

Troubleshooting


NOTE. You can use either F1 or F2 with any valid line number as arguments forthe ACQ:SHOW command. Valid line numbers are 9 – 263 for F1 and 9 – 262for F2 for the VM100, and 6 – 310 for F1 and 318 – 623 for F2 for the VM101.

After completing the ACQ:SHOW command, the video measurement set willreacquire the signal.

The waveform monitor control function allows you to simultaneously view thewaveform on a 1740A-series waveform monitor while the video measurementset measures the signal parameters. The video measurement set automaticallysends line select commands to the waveform monitor to control the monitordisplay. The resulting waveform display is the video line where the videomeasurement set is performing measurements.

The video measurement set and waveform monitor system is called a VM140when the video measurement set is a VM100. The system is a VM141 when thevideo measurement set is a VM101.

If the video measurement set is unable to control the waveform monitor, use thefollowing procedure to test the RS-232 serial port on the video measurement set:

NOTE. Use a standard 9-pin cable to connect the PC and video measurement setRS-232 serial ports. The RS-232 serial port cable used with the video measure-ment set and waveform monitor is not PC-compatible.

1. Connect a standard 9-pin cable between the RS-232 serial ports on the videomeasurement set and a PC.

2. Run the terminal emulator or communication program on the PC.

NOTE. To avoid data transfer problems, do not use a file transfer protocol suchas Kermit or XMODEM.

3. Configure the video measurement set RS-232 serial port for CONTROLmode.

4. Configure the PC RS-232 parameters to match the CONTROL mode settingsshown in Table 6–6.

Diagrams and Circuit Board Illustrations

This section contains the block diagram, circuit board illustrations, componentlocator tables, and schematic diagrams.

SymbolsGraphic symbols and class designation letters are based on ANSI StandardY32.2-1975. Abbreviations are based on ANSI Y1.1-1972.

Logic symbology is based on ANSI/IEEE Standard 91-1984 in terms of positivelogic. Logic symbols depict the logic function performed and can differ from themanufacturer’s data.

The backslash (/) preceding a signal name indicates that the signal performs itsintended function when in the low state.

Other standards used in the preparation of diagrams by Tektronix, Inc., includethe following:

� Tektronix Standard 062-2476 Symbols and Practices for Schematic Drafting

� ANSI Y14.159-1971 Interconnection Diagrams

� ANSI Y32.16-1975 Reference Designations for Electronic Equipment

� MIL-HDBK-63038-1A Military Standard Technical Manual WritingHandbook

Component ValuesElectrical components shown on the diagrams are in the following units unlessnoted otherwise:

Capacitors: Values one or greater are in picofarads (pF).Values less than one are in microfarads (�F).

Resistors: Values are in Ohms (�).

Diagrams and Circuit Board Illustrations


Graphic Items and Special Symbols Used in This ManualEach assembly in the instrument is assigned an assembly number (for exampleA5). The assembly number appears in the title on the diagram, in the lookuptable for the schematic diagram, and corresponding component locator illustra-tion. The Replaceable Electrical Parts list is arranged by assembly in numericalsequence; the components are listed by component number.

Component Locator DiagramsThe schematic diagram and circuit board component location illustrations havegrids marked on them. The component lookup tables refer to these grids to helpyou locate a component. The circuit board illustration appears only once; itslookup table lists the diagram number of all diagrams on which the circuitryappears.

Some of the circuit board component location illustrations are expanded anddivided into several parts to make it easier for you to locate small components.To determine which part of the whole locator diagram you are looking at, refer tothe small locator key shown below. The gray block, within the larger circuitboard outline, shows where that part fits in the whole locator diagram. Each partin the key is labeled with an identifying letter that appears in the figure titlesunder component locator diagrams.
